Multilingual AI detector with sentence-level insight
The detector is trained for broad language coverage rather than English-only use, which matters for international schools, multilingual newsrooms and cross-border content teams.
After the overall score, a second pass labels each sentence as Human, AI or Mixed and highlights the specific phrases pushing the score up.
Flagged passages are highlighted in the document, and a ranked impact list lets you scroll to the highest-signal sentences first.
Plagiarism checking, grammar proofreading, humanizing, an AI Editor and a presentation maker sit alongside the detector in one account.
